Why three arils won't tip the scales for an 8 lb cat
At this small quantity, the main concern isn't toxicity but whether any rind fragments hitched a ride. Three arils contain less than a teaspoon of actual fruit material once you subtract the seeds. Her stomach acid will neutralize the mild acids in the juice before they can irritate, and the seeds themselves pass harmlessly through most cats' digestive tracts.
That said, sensitive individuals might react to even this tiny amount with a single vomit episode or slightly looser stool tomorrow. Watch for her licking lips more than usual or hesitating before jumping onto favorite perches — subtle signs of nausea some cats display before obvious vomiting.
The 12-hour window when symptoms would appear
If those arils carried any problematic compounds, you'd already see signs by the two-hour mark. Since she's currently symptom-free, the likelihood of delayed trouble is very low. The seeds take about 24–36 hours to transit her system completely, so don't mistake seeing them in the litter box for an ongoing issue.
Should any reaction occur now, it would likely be mild stomach gurgling or a single episode of semi-digested food vomit. These resolve on their own within an hour if she's otherwise acting normal. Keep her water bowl freshly filled — hydration helps her system flush any irritants faster.
When to relax versus stay alert
You can breathe easy if she maintains her normal meal routine tonight and shows interest in play. Cats who feel unwell typically avoid food first, so an empty food bowl by morning is a reliable all-clear signal. No need to examine her stool unless she strains to defecate or cries while eliminating.
Stay observant only if she develops odd behaviors like repeatedly visiting the water bowl without drinking, or pawing at her mouth. These suggest possible seed hull fragments stuck in teeth or throat, which is rare with just three arils but worth checking if she seems persistently bothered.
Handling future fruit encounters
While this tiny aril snack won't harm her, it's smart to curb the habit — some cats develop a taste for sweet fruits and start begging aggressively. If she's drawn to your snacks, offer safer alternatives like small bits of cooked chicken or commercial cat treats when you're eating fruit.
Remember that pomegranate seeds aren't the real danger — it's the rind they came in. Should she ever get into the fruit's white membranes or peel, react as if she ate a toxic plant, because for cats, those parts function like one. Three arils are a non-issue, but three bites of rind would be a vet-worthy event.
